Hands down the best bearings on the market matched only by the OEM Bearings.

Over the years OEM has switched over to an all Aluminum Rod Bearing for extended reliability/longevity. Clevite/Mahle discontinued the P series rod bearings in favor of the newer designed Aluminum rod bearings.

This set of bearings with the Aluminum Rod Bearings is a good choice for stock to roughly 400AWHP. If you are shooting for higher HP PLEASE read Below

This set of bearings is still available with P Series Tri Metal Rod Bearings in 25mm and 50mm undersize until stock runs out - Choose in Options Below

Aluminum has proven over the past decade to work as a very reliable very high longevity bearing in the daily passenger car environment, BMW has been using aluminum rod bearings for many years with great success.
BUT they are NOT for Higher Power Setups.The Aluminum rod bearings do what they were designed to do, and do it very well but to do that they give up the HIGH HP capabilities the P series tri metal bearing had.

To fill that spot they have the High Performance Series Bearings which we always keep in stock.

This complete Bearing Set Includes:
(6) Pairs - A Series Rod Bearings - OR P Series Rod Bearings - Choose Below
(1) Set - P Series Main Bearings
(1) Set - P Series Thrust Washers
WE ONLY STOCK AND SELL THE CORRECT VERSION OF THIS THRUST WASHER SET.
This set of Thrust Washers is the correct thickness/specification. Unlike the version made in the Clevite Mexico plant back in 2016 that were made too thick, this set is the newer corrected version.

Clevite was aware of the issue with the Mexico Plant and corrected the issue, having them manufactured in one of their other newer manufacturing plants.
We go the extra step and verify each set is the correct specifications before putting them into our inventory.

Clevite? TriMetal? P-Series bearings are built on hardened-steel backings with extra-thin overlays

Steel backed bearings with an intermediate layer of copper-lead alloy and an electro-plated lead-base overlay.

The P Series Bearings intended for high-revving engines, especially those where the high rpm cause the rod bores to narrow.

To compensate for this distortion, they have higher eccentricity and a high crush factor.

As more and more OE manufacturers shift to aluminum bearings in OE engines, Clevite has introduced a new line of engine bearings designed to be the highest quality replacement bearings in the industry. Clevite BiMetal? engine bearings carry on the tradition and reputation that Clevite has built throughout the course of time.Clevite BiMetal engine bearings feature a 100% lead free aluminum silicon bi-metal material, which includes 60% more silicon than the leading competitor's bi-metal material for better conditioning of journal surfaces. These BiMetal bearings also offer greater wear resistance than the leading competitor's bi-metal material, as well as greater seizure resistance.Choose bearing size below.

Standard is for a new or unturned crankshaft.
.25mm/.50mm/.75mm sizes are for crankshafts that have been turned.
Your machine shop will tell you what size you need if they turned the crank.
